BANGKOK (AP) — Heavy rains threatened to delay the search for two people missing in a flooded cave in Laos on Sunday, after the rescue of five other people who were trapped underground for over a week.Finnish diver Mikko Paasi, one of the first international rescuers to arrive at the site, told The Associated Press that rains had filled the cave up to the second chamber, preventing divers from entering the cave until pumps can lower the water level.The seven villagers reportedly entered the cave last week to look for valuable minerals before being trapped by a flash flood that blocked their way out. One other villager escaped and alerted the authorities.Rescue teams from Laos and neighboring Thailand have been working together in the past week at the site in a rugged area in the central province of Xaisomboun, about 120 kilometers (75 miles) north of the capital, Vientiane. They were joined by divers from countries including Finland, Malaysia, Japan, Indonesia, France and Australia.

Several of the rescuers previously took part in the complicated 2018 cave rescue in northern Thailand that saved 12 schoolboys and their soccer coach from a flooded cave.

The rescued men are being treated at a local hospital and are doing well, Malaysian diver Lee Kian Lie, who’s taking part in the operation, told the AP on Sunday.“We interviewed them about how the deeper part of the cave looks like. We will continue to search based on the information we have, and perhaps we will be able to get to the other two,” he said.
